This is great. Thank you for your help, but let me make sure I fully
understand. Here is the looping file I use to subset the data frame,
create a tex file, and Sweave it. This results in N number of tex files
where N is equal to the number of rows in the data frame.
list <- unique(wide$stuid)
master = "master.tex"
for (i in list){
tmp1 <- subset(wide, stuid==i)
tmp2 <- paste(i, "tex", sep=".")
Sweave("fam_template.Rnw", output=tmp2)
file.append("fam_master.tex", tmp2)
}
If I follow correctly, I would need to place these commands inside the
loop as follows:
list <- unique(wide$stuid)
master = "master.tex"
for (i in list){
tmp1 <- subset(wide, stuid==i)
tmp2 <- paste(i, "tex", sep=".")
keep <- list.files(tempdir(), full=TRUE) # keep previous temp
files
Sweave("fam_template.Rnw", output=tmp2)
file.append("fam_master.tex", tmp2)
temps <- list.files(tempdir(), full=TRUE) unlink(temps[!(temps %in%
keep)]) # delete the newly created ones
}
Thank you for taking the time to look at this.

Subject: Sweave resource leak: leftover temp files
Harold, I've taken a closer look at your example and I'd call this an
Sweave bug. It creates tempfiles each time you run it, and doesn't
delete them at the end. For example:
> list.files(tempdir())
character(0)
> testfile <- system.file("Sweave", "Sweave-test-1.Rnw", package =
"utils") > Sweave(testfile, out="junk.tex") Writing to file junk.tex

Harold: a workaround for this would be to wrap your Sweave call in
something like this:
keep <- list.files(tempdir(), full=TRUE) # keep previous temp files
... Call Sweave here ...
temps <- list.files(tempdir(), full=TRUE) unlink(temps[!(temps %in%
keep)]) # delete the newly created ones
